* Make configurable (serial port, speed, flow control etc) Partly done by Cornelius Cook. * Add option to dump to file and display status on screen. * Nicer way to terminate program than Ctrl-C/KILLing it. * Lock serial ports. * Add filtering rules capability. Perhaps look at some regex libraries? * PTYs? Pipes? So we can look like a serial port to programs that expect to talk to one.
